Common Causes

• Contour file referenced in program is missing or not loaded into memory
• Insufficient available memory space on the control for storing contour data
• Incorrect contour file path or filename in the NC program block
• Contour directory not properly initialized or corrupted in system memory
• Program block syntax error referencing a non-existent contour definition

Troubleshooting Steps

1. 1Verify the contour file exists in the correct directory on the control and check the exact filename matches the reference in the NC program at the indicated line number
2. 2Load or reload the required contour file into the control's memory using the file management interface before executing the program
3. 3Review the program block syntax at line %1 and confirm the contour call statement is correctly formatted according to 840D/828D specifications
4. 4Check available memory space on the control and clear unnecessary files or data if memory is critically low; restart the control if needed
5. 5Verify the contour directory path is correctly configured in the system parameters and that the contour file has proper read/execute permissions
